Station-class surge arrester 3EQ5, silicone housing on composite hollow core, 3EQ family, HVDC and AC station applications

• Member of the 3EQ composite surge arrester family in the official product hierarchy, alongside 3EQ1, 3EQ3 and 3EQ4; also listed under HVDC arresters, insulators & resistors
• 3EQ family design per the HV surge arrester product guide: silicone rubber molded onto an FRP hollow-core tube with directional pressure relief devices at both ends
• The 3EQ hollow-core construction is shatterproof and retains at least 75 percent of its mechanical strength even after pressure relief — suited to heavy seismic activity and extreme wind loads, and usable as post-insulator replacement in substations
• The published product guide tabulates ratings for the 3EQ1, 3EQ3 and 3EQ4 lines; 3EQ5-specific ratings and specifications are provided on request
